Abstract (en)
[origin: EP0592211A1] A method of forming a seamless cylinder shell in which a nickel sheet is clad to a steel sheet so that the sheets are uniformly bonded throughout and a composite sheet is formed. The cladding is preferably effected by explosive cladding. The composite sheet is then preferably cut into a circular blank before further processing. The circular blank is subjected to an oxalic acid pre-treatment to retain a lubricant on the two opposed surfaces thereof and is thereafter lubricated with the lubricant. The circular blank is preferably cupped, relubricated, and drawn into the seamless cylinder shell. The seamless cylinder shell can be finished into a seamless gas cylinder by spinning one end of the cylinder into a cylinder head, internally threading the formed cylinder head, and then heat treating the cylinder. <IMAGE>
